The E! star is quite the style icon, and that doesn't change when she has a bun in the oven. Scott Disick's lady, who officially confirmed over the weekend that she's expecting her third child, stepped out for an orthodontist appointment in the Hamptons earlier today, and looked just as chic as ever.
